PRIMARY BATTERY.

Specification of Letters Patent.

Patented Apr. '7, 191d.

To all whom '02? may concern:

Be it known that I, CHARLES B. SoHonN- MEHL, a citizen of the United States, and resident of \Vaterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvetrode.

It is the purpose of my invention to provide novel means for suspending the above class of assembled elements from the top of the jar irrespective of whether a cover be employed or not; to provide a construction which is equally adapted for both the compressed copper oxid plate and the loose cop per scale when contained within a cylindrical basket and used in connection with a suitable form of zinc element; further to provide a novel form of suspension which will permit the assembled elements to be readily placed in or removed from the jar without disconnecting the said elements or operating any nuts or screws as has heretofore been necessary when such elements were suspended from the cover, and finally to so arrange and construct the suspending means as to dispense with the use of the cover, and thereby saving the cost of such cover.

My invention consists further in the details of construction and combination of parts hereinafter more fully described and claimed.

In the accompanying drawings forming a part of this specification Figure 1, shows a side elevation of an assembled cylindrical basket and zinc form of element suitably suspended within a jar by my improved form of suspending means. Fig. 2, is a plan view of the construction shown in 1. Fig. 3, is a similar side elevation of a popular style of compressed copper oxid plate and zinc plate form of assembled elements suspended within a battery jar and illustrating my improved suspending means as applied to that form of assembled element. Fig. 4, is a, detached side elevation, ofl the assembled element shown in Fig. 3 and Fig. 5, shows my invention applied to still another form of holding frame, carrying a compressed copper oxid plate and zinc plates, forming the electrodes.

Referring in detail to the characters of reference marked upon the drawings 10 indicates an ordinary porcelain containin jar of suitable dimensions and designed to %l0ld the exciting fluid, and in which the assembled element is suspended.

The character 11 represents a cylindrical form of perforated basket as shown in Figs. 1 and 2, for containing oxid of copper scale to form thenegative electrode, This basket may be of any preferred construction and as shown includes two vertically disposed rods 1212 for retaining theend caps of the basket in place, and for supporting the basket in position. A pair of insulating blocks 13 and 14 are also mounted upon the upper end portion of these two rods and'scrves to insulatively support a cross yoke 15 from the said rods. A cylindrical zinc element 16 is hung from the two outer end portions of this yoke in a way to encircle the basket and to form the coacting positive electrode. A field wire 17 is detachably connected to this element by means of a nut 18 secured. to one of the hanger rods 19 as is clearly shown in Fig. 1. A second positive element 20 in the form of a zinc rod is connected with the cross yoke 15 and is suspended centrally within the negative basket so as to insure an action on both sides of the cylindrical negative electrode, to increase the efficiency of the battery. The suspending means as applied to this assembled element consist of a metal strip 21, the intermediate portion. of .which is secured to the top face of the insulating block 13 by means of the rods 12 passing through the said yoke and is provided with nuts 22 for clamping the strip 12 to the block.

The outer end portions of the strips are deflected upward and have their extreme ends turned down to form a hook to engage the top edge of the jar from which the assembled element is suspended. This suspending strip, through the medium of the rods 12, is connected to the negative element and is provided with a binding screw 24; for the attachment of asecond field wire 25. This form of assembled cylindrical element is designed to be hung from the cover of a jar by a single suspending rod 25 as suggestedy dotted lines in Fig. 1., and theresembled elements, and wherein 11 indicates the negative plate electrode arid 16 the positive zinc plate electrode. A smaller metal frame is secured to the edge portions of this negative plate, and as shown in Figs. 3 and 4 includes an inverted V shaped wire QG-for, engaging thev side and edge portion of the plate and sheet metal channel cross piece 27 for engaging the lower edge of the plate. A loop 26 is formed in the top cross portion of the wire to cover an insulating block 28. A bolt 29 is passed through said insulating block for the attachment of the zinc or ositive plates 16 which are arranged on either side of the negative plate and at an equal distance theretgom. The field wire 17 is secured to the", olt 29 to form! the electrical connection with the positive plates. In this fiorm of construction I elect to form the sus-, pendingmeansin two parts 21, WlllCh, as shown 1n Figs. 3 and 4, .comprise two sheet metal strips that are punched at 21 to allow the, wire side portions of the frame to be passed therethrough. The lower portions of these strips are seated against the respective side edges of the negative plate and beneath the wire side portions of the frame, so as to.

insure a good mechanical and electrical connection. The upper part of these side strips like that in the other forms are turned down to form hooks to engage the top edge of the ar. J The construction shown in Fig. 5, includes a po ular form of plate holder made largely of ciiannel sheet metal and including side channel pieces 21 connected'top and bottom with cross members 26 'and 27. The side pieces 21 have their edges disposed back,

circuited,whenset up in series, should these hook portions happen to be placed one against the other.

Thei forego'iiig construction enables me to suspend most any of the popular forms of assembledelements, from the top edge of a battery jar and central therein in a manner to permit of them bemgreadily inserted and removed as, occasion may require and with-v out the use of a cover, or bridge.

Having thus described my invention what I claim and desire to secure by Letters Patent is- In a primary battery of the class described, the combination with an assembled element including positive and negative electrodes insulatively connected together and carried by a single holding frame, of means for suspending the said elements with a battery jar and below the top thereof, comprising' longitudinally disposed side strips secured to and forming a part of the frame and having upwardly and outwardly disa posed hangers the ends of which are dis-- posed down to engage the top edge of a bat- 'tery-jar and to prevent lateral movement of the element within the jar, and a binding screw attached to one of said ends.
